PUMPING APPARATUS FOR OIL-WELLS.

Specification of Letters Patent.

Patented Oct. 27, 1908.

Application filed January 17, 1908. Serial No. 411,265.

To all whom it may concern:

Be it known that I, WALTER C. BECKWITH, a citizen of the United States,residing at Fostoria, in the county of Seneca and State of Ohio, haveinvented Certain new and useful Improvements in Pumping Apparatus forOil-Wells, of which the following is a specification, reference beinghad therein to the accompanying drawing.

My invention relates to improvements in pumping apparatus for oil wells.

The object of my invention is to provide a pumping apparatus of thischaracter, which does away with the polish rod, and its packing, andalso with the usual jack, which produces a much more simple, andeffective pump, thus doing away with the frequent repacklng of thepolish rod.

Another object of my invention is to provide a pump of this character,in which the sucker rod can be readily removed without disturbing thepacking of the working part of the pump.

A still further object of my invention is to provide a more simple,cheap and effective pump to accomplish the above results.

In the accompanying drawings, Figure 1, is a side elevation of myimproved pum ing apparatus. Fig. 2, is a vertical longitu inal sectionalview showing the pulley wheel or drum in full lines. Fig. 3, is atransverse vertical sectional view. Fig. 4, is a side elevation of amodified form of mechanism for operating the pump.

Referring now to the drawings, 1 re resents the well casing of an oilwell, and w ich usually carries a stuffing box through which the polishrod extends, and works u and down. My invention is designed to o viatethe use of this stuffing box, and also the use of the polish rod, andalso any packing whatever for the sucker rod.

The invention consists of a casing or housing 2 having adownwardly-extending circular portion 3 having an opening therethrough,and communicating with the housing, and having internal threads 4 bymeans of which it is screwed upon the upper end of the well casing. Theportion 3, as shown in the drawings, is at one side of the housing andforms a support for the housing, and also a communication with the wellcasing. This portion 3 extends upwardly and forms a vertical space atone side of the casing, as indicated at 3, and which communicates withthe casing, as shown in Fig. 2, and which will be hereinafter more fullydescribed.

The housing, as shown, is made in two sections 5 and 6, the uppersection 6, as shown, being removable, and the two sections provided withoutwardly-extending abutting flanges 7 and 8 between which a packing 9is placed for forming a tight housing for the purpose hereinafter setforth.

The sides of the lower sections are provided with openings which aresurrounded by stuffing boxes 10 and 11, and passing through the openingsin the lower section and through the stuffing boxes, is a shaft 12 whichextends out beyond the stuffing boxes. Within the housing on the shaft12 is a drum or pulley 13 which is of such a diameter that it extendsinto the vertical passage 3 at the side of the housing. This passage, asshown, is directly over the well casing, and within the casing is thesucker and sucker-rod 14 to which is attached a chain 15 by means of thedetachable coupling 16. The upper end of the chain is secured to theouter periphery of the drum 13, as indicated at 16, and by rocking thedrum, as will be hereinafter more fully described, the chain will beraised and lowered, and the sucker-rod 14 raised and the weight of thesame causes it to drop down, and thus the oil is drawn upwardly withinthe housing.

The drum 13 has a cut-away portion 17 which when turned around oppositethe vertical passage 3 leaves an unobstructed passage, whereby when theupper portion of the housing is removed the sucker-rod and the suckercan be removed without disconnecting any of the working parts, or any ofthe packing.

The outer ends of the shaft 12 on the outside of the stuffing boxes, areprovided with arms 19 and 20 which are keyed upon the shaft and extendupwardly over the housing and are drawn inwardly, as indicated at 21 and22, to brin the upper ends thereof closer together. etween the upperends of these arms are secured the shackle rod 23 to which is imparted areciprocating movement which rocks the arms 19 and 20, and oscillatesthe drum for working the pumping apparatus, as heretofore described.

The stufiing boxes 10 and 11 around the shaft are for making a tightjoint therewith, as the housing is filled with oil, and thus preventsthe waste of any oil. The housing is provided with a discharge pipe 24from which the oil is conveyed to the desired point and may be connectedto the casing at any desired point. 7

The housing at the opposite end to which is attached the well casing isprovided with feet 25 which more rigidly support the casing.

In Fig. 4 instead of having the arms 19 and 20 extending upwardly, Iprovide downwardly-extending arms 26 provided with a series of openings27 by'means of which the forked member 28 is secured thereto, and byattaching said forked members at different points on the arms 26 themovement of the drum is varied and thus the throw of the sucker rod isregulated.

y scribed, it will be seen that through the medium of the drum 13 andchain 15 there is a straight vertical pull upon the sucker-rod. Therebeing no polish rod, and also no packing for the sucker-rod, when it isdesired to remove the same none of the working parts i of the pump haveto be disturbed, but it is only necessary to remove the section 6 of thecasing and turn the drum 13 around so that the cut-away portion 17 isaround opposite the passage 3.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is

1. The combination with a well casing, a piston rod therein, a tighthousing secured upon the upper end of the casing, a drum within thecasing and having a flexible connection with the piston rod, and saiddrum having a cut-away portion in its periphery, whereby the piston rodmay be removed through the housing without disturbing the drum.

2. The combination with a well casing, a piston rod therein, a tighthousing secured upon the upper end of the casing at one side, a drumwithin the casing and its outer periphery extending over the center ofthe well casing, a flexible connection between the drum and piston rod,and said drum having a cut-away portion in its periphery, whereby thepiston can be removed through the housing without disturbing the workingparts of the drum.

3. The combination with a wellcasing, of a tight housing secured uponthe upper end of the casing, a shaft extending through the housing, adrum carried by the shaft within the housing, a sucker-rod within thecasing, a chain having one end secured to the outer periphery of thedrum and the other end secured to the sucker rod, and means carried bythe shaft on the outside of the housing for rocking the same, the saiddrum having a cut-away portion which can be brought over the well-casingfor removing the pump-piston therefrom.
